PyCharm でCData ODBC Driver for Dynamics NAV を使ってみた

Dynamics NAV にODBC データソースとしてPyCharm から連携。

CData ODBC Drivers は、ODBC をサポートするあらゆる環境から利用可能です。 本記事では、PyCharm からのCData ODBC Driver for Dynamics NAV の利用を説明します。ODBC Deriver をデータソースとして設定する方法、データソースをクエリするPyCharm のベーシックな方法を含みます。

To begin, this tutorial will assume that you have already installed the CData ODBC Driver for Dynamics NAV as well as PyCharm.

Pyodbc をプロジェクトに追加

Follow the steps below to add the pyodbc module to your project.

  1. Click File -> Settings to open the project settings window.
  2. Click Project Interpreter from the Project: YourProjectName menu.
  3. To add pyodbc, click the + button and enter pyodbc.
  4. Click Install Package to install pyodbc.

Dynamics NAV への接続

You can now connect with an ODBC connection string or a DSN. See the Getting Started section in the CData driver documentation for a guide to creating a DSN on your OS.

Before you can connect, OData Services will need to be enabled on the server. Once OData Services are enabled, you will be able to query any Services that are published on the server.

The User and Password properties, under the Authentication section, must be set to valid Dynamics NAV user credentials. In addition, you will need to specify a URL to a valid Dynamics NAV server organization root and a ServerInstance. If there is not a Service Default Company for the server, you will need to set the Company as well.

Below is the syntax for a DSN:

[CData DynamicsNAV Source] Driver = CData ODBC Driver for Dynamics NAV Description = My Description http://myserver:7048 User = myserver\Administrator Password = admin ServerInstance = DYNAMICSNAV71

Dynamics NAV へのクエリの実行

Instantiate a Cursor and use the execute method of the Cursor class to execute any SQL statement.

import pyodbc cnxn = pyodbc.connect('DRIVER={CData ODBC Driver for DynamicsNAV};http://myserver:7048;User = myserver\Administrator;Password = admin;ServerInstance = DYNAMICSNAV71;') cursor = cnxn.cursor() cursor.execute("SELECT Name, Prices_Including_VAT FROM Customer WHERE Name = 'Bob'") rows = cursor.fetchall() for row in rows: print(row.Name, row.Prices_Including_VAT)

After connecting to Dynamics NAV in PyCharm using the CData ODBC Driver, you will be able to build Python apps with access to Dynamics NAV data as if it were a standard database. If you have any questions, comments, or feedback regarding this tutorial, please contact us at support@cdata.com.
